Next control assembly 506 will read degree of superheat SH from control assembly 559 reading of data of each indoor set 20,30,40 during cooling operation, reads degree of supercooling SC (the 103rd stage) when heating running.Above-mentioned action can be claimed to indoor set by communication component 500 by control assembly 506 and be achieved.
Each indoor set is in the process of action, and the pressure transducer 210 of each indoor set can detect force value, and control assembly 506 then can read these detected force value.Above-mentioned force value is low pressure PL detected value when cooling operation, is high pressure P H detected value (the 106th stage) when heating running.
Capacity Q, the degree of superheat SH of each indoor set of each indoor set that utilization reads by said process or low pressure PL or these data of high pressure P H of degree of supercooling SC and each indoor set just can calculate the power consumption QS of each indoor set by following arithmetic expression 1 and arithmetic expression 2.
Arithmetic expression 1:
Power consumption QS=[capacity Q * benchmark low pressure a during cooling operation]/[degree of superheat SH * low pressure PL]
Arithmetic expression 2:
Power consumption QS=[capacity Q * benchmark high pressure b when heating running]/[degree of supercooling SC * high pressure P H]
Here, said reference low pressure a is 5kgf/cm
2, benchmark high pressure b is 20kgf/cm
2
Next, control assembly 506 calculates (the 112nd stage) to the accumulative total power consumption SQS of each indoor set.Each indoor set carries out the course of action in above-mentioned 109 stages of the 100th stage to the repeatedly in the process of running, thereby calculate the power consumption of present running status, will be added up just can draw above-mentioned accumulative total power consumption SQS in the power consumption that draw like this is during some cycles.Above-mentioned some cycles refers to the cycle of calculating the electricity charge.
The accumulative total power consumption SQS of control assembly 506 each indoor set that can will calculate all adds up then, thereby calculates whole power consumption TSQS (the 115th stage).
If the whole power consumption TSQS that calculates and the power consumption of each indoor set are compared, so just can draw the electricity charge ratio (the 118th stage) of each indoor set in above-mentioned the 115th stage.If the electricity charge ratio of each indoor set that so calculates and the whole electricity charge are multiplied each other, so just can calculate the electricity charge (the 121st stage) of each indoor set.The electricity charge of each indoor set that control assembly 506 will calculate like this send each indoor set to by communication component 500, and the control assembly 559 of each indoor set can show (the 124th stage) with the electricity charge separately by control display unit 565 then.
